as per title i just overclocked my cedar mill intel 4-631 reversion d0 to 4.5 man is this crazy i just sold my xeon x5460 stepping c0 and i ordered a xeon x5470 so as i am waiting to get that cpu i said oh what the heck let me put in my old cedar mill cpu and see what i can do with it 4.5 ghz is not all that bad shoot over the stock 3.0ghz id say its an improvement and it is hyper threading enabled so overall man am i loving mine my brand new 40$ asrock p5b-de mobo. Altough i couldnrt get it any higher than that i dont know why i tried to max out the voltage on the cpu and NB. oh well now to wait for the new cpu.
